AngLegs ™ come in six lengths that easily snap together to motivate students to explore plane geometry on their desktop or the overhead projector. Students will discover what happens as they use the same length legs verses different length legs to build various polygons, as they attach additional legs they study polygon heights, calculate their areas, find center points and much more! When two AngLegs ™ of any length are snapped onto the special 4 ” protractor students will explore angles, add a third leg for triangles, a forth for quadrilaterals, and so on.

This 74-piece set consists of 72 AngLegs ™12 each of six different lengths in six colors and two snap-on View Thru ™ protractors.

This exciting new manipulative includes a set of 15 activity cards, divided into three sections for grades K-2, 3-5 and 6-8.

Model geometry activities for the whole class using our new demonstration compass as students follow along at their desks with Bullseye® Compasses (45701). Draw circles 2"-32" in diameter, construct and measure angles with built-in protractor, and measure length in customary or metric scales with ruler edges. Suction cup fits securely on board for accurate measurements and construction. Translucent plastic improves accuracy by allowing you to see lines, angles and shapes as you draw them. Made of shatter-resistant SAFE-T® Plastic. Measures 19.75"L x 4.25"W.

This 4-in-1 drawing tool can be used as a compass, a ruler in inches, a ruler in centimeters and a protractor. The opening in the Direct View ™ compass point provides the easiest, most accurate location for all circle constructions. Quick-Set ™ radius indicator allows for immediate comparison of inches and cm. Built-in protractor measures and constructs angles. Made of SAFE-T ® Plastic ® for a safer, longer lasting tool. Circles can be drawn with diameters from 1” to 9 3/8”.

Help students to delve into plane geometry! Great for hands-on activities such as perimeter, area, identification of shapes and attributes, spatial reasoning, similar triangles, parallel lines cut by a transversal, show examples of angle bisectors that form perpendicular angles to opposite sides and more. 82 piece set includes 2 protractors, 13 double-sided work cards with 23 activities, and GeoStix™ in 8 different lengths (2.5cm to 25cm).

The magic of gravity pushes the spheres through the Geomag gravity motor spiral. A magical and eco-friendly system that uses the invisible forces of attraction and repulsion to set in motion the models. Starting at the base of the system, the weight of the spheres creates a never-ending spiral that kickstarts a real gravity motor. This set contains 11 magnetic rods, 32 spheres and 126 plastic mechanical elements. Gravity is the innovative evolution of the Geomag mechanics line. Developed with expert players in mind, the new construction system is based on an innovative "gravity motor": this uses the weight of the Geomag spheres to Kickstart the mechanisms and movements of the Geomag mechanics structures. The motion is provided by the invisible forces of gravity and magnetism, without using electricity or batteries. The play experience is based on these fundamental principles of physics. Mechanics gravity is a STEM product that can truly stimulate curiosity and inspire to learn more about science.

Mechanics gravity magnetic race track harnesses the invisible forces of magnetism and gravity through original and surprising means. The spheres inside the circuit are set in motion by an innovative magnetic cannon that uses the force of attraction of the accelerating magnet. This set contains 2 magnetic rods, 9 spheres and 104 plastic elements - all the essentials needed to build freely and create chain reactions.

The movement of the mechanics models wins over gravity with the gravity shoot & catch set. Thanks to the magnetic motor, the Geomag spheres move up along a never-ending spiral and reach a circuit of amazing magnetic tricks. Here is the "stop&go" trick in action: two magnetic rods, positioned with opposite polarities, can keep one or two spheres perfectly still inside a chute. When a third sphere joins the other two from above, it is itself trapped by the magnet and the lowest positioned sphere is released to continue its journey along the circuit. This gravity set contains 11 magnetic rods, 36 steel spheres and 196 plastic mechanical elements. These gears are essential to harness the forces of gravity and magnetism.

Calling all future engineers. The up & down circuit set is the most complete one in the gravity range and is based on the movement of the spheres. Their weight moves a never-ending spiral and starts a real gravity motor. In this system of magnetic gears a second spiral is activated, allowing the spheres to ascend as if they were in an elevator. Once they reach the top of structure, the spheres enter a circuit full of amazing magnetic tricks and then descend once again to keep the gravity motor active. At the heart of this circuit are the 330 pieces contained in this set: 21 magnetic rods, 39 steel spheres and 270 plastic mechanical elements.
